Joshua Peraza 5e1c53a442 android: truncate lower of two overlapping modules 
Previously, the processor truncated the upper of two
overlapping module ranges to compensate for incorrect
reporting of module ranges by the Breakpad client.
Crashpad correctly reports module load ranges, so
this truncation strategy is no longer necessary.

However, when partitioned libraries are used, the base
library may have a range which encompasses the other
partitions. When this is combined with the truncate
upper merge strategy, the base library's executable
segment is truncated causing symbolization failures.

This patch changes Android's merge strategy to truncate
the lower range (which is still the base library, but
this strategy truncates from the high end of the
library's range, instead of its base).

Bug: b/149845120

Breakpad

Breakpad is a set of client and server components which implement a crash-reporting system.

Getting started (from master)

  1. First, download depot_tools and ensure that they’re in your PATH.

  2. Create a new directory for checking out the source code (it must be named breakpad).

    mkdir breakpad && cd breakpad

  3. Run the fetch tool from depot_tools to download all the source repos.

    fetch breakpad
cd src

  4. Build the source.

    ./configure && make

    You can also cd to another directory and run configure from there to build outside the source tree.

    This will build the processor tools (src/processor/minidump_stackwalk, src/processor/minidump_dump, etc), and when building on Linux it will also build the client libraries and some tools (src/tools/linux/dump_syms/dump_syms, src/tools/linux/md2core/minidump-2-core, etc).

  5. Optionally, run tests.

    make check

  6. Optionally, install the built libraries

    make install

If you need to reconfigure your build be sure to run make distclean first.

To update an existing checkout to a newer revision, you can git pull as usual, but then you should run gclient sync to ensure that the dependent repos are up-to-date.

To request change review

  1. Follow the steps above to get the source and build it.

  2. Make changes. Build and test your changes. For core code like processor use methods above. For linux/mac/windows, there are test targets in each project file.

  3. Commit your changes to your local repo and upload them to the server. http://dev.chromium.org/developers/contributing-code e.g. git commit ... && git cl upload ... You will be prompted for credential and a description.

  4. At https://chromium-review.googlesource.com/ you'll find your issue listed; click on it, then “Add reviewer”, and enter in the code reviewer. Depending on your settings, you may not see an email, but the reviewer has been notified with google-breakpad-dev@googlegroups.com always CC’d.
